pls help me regarding Maths round up function.....
Hi,
I have some values on my webpage displaying like
1.22333333333
2.33333344444
2.33377777777
etc.
Here I want to display values upto 2 decimal places correct.
i.e, 1.22333333333 should be dislayed as 1.22
2.33333344444 should be dislayed as 2.33
2.33777777777 should be dislayed as 2.34
& so on....
How to do this in ruby?????
Is there any function???
Thanx in advance.

float calculation error
Hi
I have the following values
pActualCost = 33.00
pPaymentCost = 29.99
So this calculation should leave me with 0.01
pPaymentDifference = pActualCost - pPaymentCost
however when doing this in rails, it returns 0.00999999999999801
has anyone got any suggestions to whats going wrong and how I can
correct this
Thanks
Scott
